Specification of Letters Patent.

Patented May 31, 1910.

Application filed August 19, 1909. Serial No. 513,669.

To all whom it may concern:

Be it known that I, REUBEN C. BIOKER, a citizen of the United States,residing at Canal Dover, in the county of Tuscarawas and State of Ohio,have invented certain new and useful Improvements in Molds, of which thefollowing is a specification, referenee being had to the accompanyingdrawings.

This invention relates to improvements in molds and more particularlyone for use in molding lead packing rings used in pipe joints, such asthe one set forth in my Patent No. 925,946, granted June 22, 1909.

The object of the invention is to provide a simple and practical deviceof this character by means of which lead packing rings may beexpeditiously and economically made.

Vith the above and other objects in view, the invention consists of thenovel construction, combination and arrangement of parts, hereinafterfully described and claimed, and illustrated in the accompanyingdrawings in which-- 7 Figure 1 is a plan view of the improved mold. Fig.2 is a side View. Fig. 3 is an end View, and Figs. t and 5 arelongitudinal and transverse sections.

Referring more particularly to the drawings, 1 and 2 denote the twomembers of the mold, which latter are adapted to mold a lead packingring with beveled or angular ends. These mold members are ofsubstantially elliptical shape and the outer member 2 is dividedlongitudinally into two similar half sections 3, 4c. Each of said halfsections has a flat base portion 5 and an upstanding rim 6 around itscurved outer edge. The sections 3, 4 are hinged together by a verticalpin 7 passed through recessed overlapping lugs 8 formed on the rims orflanges 6 at one end. The opposite ends of the flanges 6 are formed withoutwardly projecting recessed lugs 9, 1.0 in the form of which ispivoted at 11 a clamping bolt 12. This bolt is adapted to swing into therecessed end of the lug 10 on the opposing section and receives on itsthreaded end a hand nut 13.

The inner mold member 1 comprises a flat plate 14: of elliptical shapeadapted to rest upon the flange or rim 6 and formed upon its inner faceat a suitable distance from its edge with a projecting elliptical shapedrim 15. The latter is adapted to enter the outer member 2 and to restupon its portion 5 whereby a substantially annular space 16 is formedbetween the two members for the reception of the lead or other materialfrom which the packing ring is made.

For the purpose of retaining the two mold members in operative position,a clamping member 17 is employed. This member is in the form of a bolthaving one end passed through a centrally arranged opening in the plate14L and provided with two lock nuts 18 arranged on opposite sides ofsaid plate whereby the bolt is retained in position. The opposite end ofthe bolt projects through opposing recesses 19 formed in the straightinner edges of the plates 5, and said end of the bolt is provided withan inner nut 20 by means of which the two members may be securelyclamped together. The notches or recesses 19 are made oomparatively longso as to form a slot to permit the outer mold member 2 to be shiftedlongitudinally with respect to the inner member for the purpose ofvarying the thickness of the molded packing ring. Owing to thisadjustment it will be seen that the lead ring may be made of irregularthickness, that is, a little heavier on one side and correspondinglylighter on the other side to suit various joints in soil pipe flashingetc.

To permit the lead to be poured into the space or cavity 16 a fillingopening is provided in the outer member 2, such opening being formed byopposing notches or recesses 21 formed in the straight inner edges ofthe plates 5 of the half sections 3, 4:. By making the filling openingin this manner it will be seen that should any of the lead project intothe opening, it will not interfere with the separation of the moldsections.

Having thus described the invention what is claimed is:

1. A mold of the character described, comprising with continuoussurrounding flanges, the flange of one being adapted to enter within andoppose the flange of the other, and a centrally arranged fastening meansfor uniting the members.

2. Amold of the character described, comprising two flanged members, theflange of one being adapted to enter within and oppose the flange of theother, and a clamping bolt for uniting the two members, one of thelatter having an elongated opening to retwo members formed on theiredges ceive the bolt whereby said members may be shifted longitudinallywith respect to each other to vary the size of the mold space betweentheir flanges.

3. Amold of the character described, comprising two members havingcontinuous surroundin flanges formed on their outer edges, the ange ofone being adapted to enter within and oppose the flange of the other,one of said members being composed of hingedly connected half sections,a fastening uniting said half sections, and a centrally arrangedfastening means unltlng the two members.

4- Amold of the character described, comprising an inner memberconsisting of a plate provided with a central opening and formed on itsinner face adjacent with its edge with a surrounding flange, an outermold member divided longitudinally into two half sections, each of thelatter having a plate formed with a straight inner edge and asurrounding flange at its outer edge said straight inner edge of thehalf sections being formed with opposing centrally arranged elongatednotches and with opposing notches arranged adjacent one end, the lastmentioned notches forming a filling opening, a hinge connection unitingone end of the half sections, a detachable fastening means uniting theopposite ends of the half 7 sections and a clamping bolt having one endsecured in the central opening in the plate of the inner mold member,and its other end adjustable in the elongated centrally arthe otherwhereby a mold space is formed between the two flanges and plates, and acentrally arranged fastening detachably uniting the two plates.

A mold of the characterdescribed com prising two opposing plates, onehaving a surrounding flange at its edge, and the other havlng acontinuous surrounding flange adacent to its edge, the last mentionedflange be ng adapted to enter within the flange of the other whereby amold space is formed between the two flanges and plates, a Celltrallyarranged screw swiveled in one of said plates, the other being formedwith an elongated opening to receive the screw, and a nut engaged withthe screw for uniting the two plates and retaining them in ad justedpositi n.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses.
